On TV this Friday: The CW improvs a new season of Whose Line Is It Anyway?, The Neighbors say Cheers to Debbie’s mom, A.N.T. Farm‘s series finale marches to The Big Apple and Helix targets an assassin. As a supplement to TVLine’s original features (linked within), here are 10 programs to keep on your radar.

8 pm A.N.T. Farm (Disney Channel) | Series finale: Zoltan attends the opening of the new flagship Z-Store in New York, while Chyna meets a street performer (Shake It Up!‘s Roshon Fegan) who is keen on impressing her.

8:30 pm The Neighbors (ABC) | Debbie’s off-kilter mother (guest star Rhea Perlman, Cheers) invites the Weavers to San Diego so they can meet the special fella in her life – but Debs will only go if Larry and Jackie tag along. (Watch a sneak peek.)

9 pm Grimm (NBC) | A double homicide leads Nick and Hank to a traveling circus, where the mysterious performers are not what they seem. Being Human‘s Sam Witwer (and his impeccable smolder) guest-stars. (Did you hear the renewal news?)

10 pm Hannibal (NBC) | When the team is called to a meadow, they discover a body whose head has been converted into a beehive (a most bee-a-utiful sight, really). Katz continues working on the mural killer case.

10 pm Helix (Syfy) | In the show’s penultimate episode, Alan, Walker, Hatake and Daniel set up a trap for a deadly assassin who has been sent to retrieve both the virus and the cure.

10:30 pm Betty White’s Off Their Rockers (Lifetime) | Betty starts a new workout routine, and her protegé helps her answer some fan mail.
